Well every so often at the moment the engine temp guage (OEM) is going rather high. I recently did a clean out of sensor sender as guage was going erratic. The elect. fan is working. When air con. is on temp. goes up more. Questions: Could it be due to the extreme hot weather conditions? New exhausts were put on and I did notice that the idle rpm is slightly up - around 1 instead of below which could lead to overheating. When I noticed this I thought perhaps the ECU needs resetting - so undid battery etc. but the idle RPM may be still higher than should be - would ECU reset help redo idle? Anyway the wife is out in the ZX at moment and I've told her …

anyone know what wires I need to connect to? According to the wiring diagram: white = +12V then i need IG1 output & IG2 output, now do these correspond to the black/white & black/red wires on the back of the ignition switch? For an APEXI timer by the way..... Thanks Jon... :)

Hello there folks, I;ve checked the small print on my warranty policy and found that the turbos are only covered if they6 fail suddenly rather than by wear and tear. All this means I'm actually contemplating changing them myself. I'm not kidding myself in that I know its a mammoth job. I know its possible to do it with the engine in-situ and this is the way I'll have to try it as I don't have any way or removing the engine. Has anyone done this? Annoyed with myself more than anything as I should have checked the policy more thoroughly. Cheers. Martin.

I just replaced the rear transmission mount on my 1992 import auto n/a. The old one looked ok though, no splits in the rubber, seemed soft enough. When they deteriorate can you tell by looking at it ? Has anyone replaced theirs and the old one looked knackered ? Thanks John

Looks like i am going to have to change the front discs as they squeal constantly. I have tried everything but looks like the visa card is going to have to appear again! At present they are Brembo R33 discs, 330mm i think? What is the largest size i can get? I think i seen somewhere about 365mm discs? I will also be changing to Porterfield pads. Are the RS4's the best?

anyone hear had gurgleing sounds comeing from the n/s front wing? i spent 3 days bleeding the cooling system thinkin it was an airblock or headgasket. but it turned out 2 b some exhaust condensation valve stuck open under the wing. dont know if anyones interested 2 know that but it may save u some hassle.:D

Hi all, My clutch seems to be misbehaving and is getting worst with each day that passes. Symptoms are as follows: Serious problems putting it in first gear, no grinding of spinning cogs but it takes a lot of force and eventually clicks into place. 2nd gear is the same but only when stationary (are all the gears) when moving getting into 2nd isn't a problem, but 3rd gear crunches. Sometimes i.e. 1 out of 20, first gear will slip in without a problem. Is this a case of adjustment needed or are we looking at a new clutch or something else ?

Hey dudes, I know there already has been a post bout shocks, but it didnt answer all my quesions so wondering if anyone could help? I have a 95 TT import and it appears all the oil has come oout of one of the rear shocks :S so its bit bouncy any way im gonna replace the rear shocks. does anyone have any recommendations and where to get them from and how much roughly they cost? also will the uk spec stock shocks fit the jap spec zxs or do i need to get jap spec ones? Cheers peace out y'all

just found out my cat is blowing. would this make my car run rough. ie loss of power and feels like running on 5 or less. cheers ...lee

Hi Guys, Well, those of you that know me that I have had no luck with this car and the bad luck continues. The problem would see to be with the auto gearbox, which is a UK car but has a seperate oil cooler. I went to my friends this morning and parked up which was a 2 miles drive. I went back to my car and then reversed off the drive and put the car into neutral whilst my friend pulled oof the drive. I then out the car into drive and proceeded to drive up a slight hill anout 100m and then the car seemed to just lose drive. I tried to put the car into 1st and 2nd but no difference. I then left the car for a bit and started it back up, this allowed me…

i need a low beam bulb from nissan, they say itll cost me £109!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! i say *****cks , please someone tell me i can get these cheeper somewhere else, first relpy gets a prize;) tim

Guys, A quick straw poll....Apart from SE of course, Who would be the best bet to replace my turbos? I don't wish to start a war here, I am just canvassing opinions as I have warranty cover but only if they have failed and not worn out...! I have to pay for their removal, and if they are broken, I get my money back, if they've worn out, I have to pay. Many thanks, Phil.

After filling in the necessary registration forms to register my newly imported jap import, i've received the tax disc through the post this morning.... But nothing else (apart from the docs I sent them ie mot). I was led to believe that once I'd receieved the tax disc (plus other docs?) I could go and get the reg plates made up so I could actually drive the vehicle rather than wait 2-3 weeks for a logbook? But the only thing I have is the tax disc? I get a sneaky suspicion that the dvla haven't sent me all that they should have :angry:. Has anyone got reg plates made up on a tax disc only? btw, who makes up the square number plates for the rear …

My Zed is 1992 and I have workshop manual on disc from Luke. Is there any point in paying £10 to get the Haynes book which is really only z31? Only a tenner but my arms are short and my pockets deep so don't like to waste money - 's nearly 3 gallons o' petrol.:rolleyes:

Hi Guys, There is an ECU chip for sale on e-bay.com, item number 2426533494... Description:- 300zx 90-93TT Chip ecu 370cc or 555cc 70hp+...... What do you guys think, worth a look or not? Baz

i need 2 lower my zed but a couple of companys say no one does them. but iv seen loads of lowered zeds any info much appreitated

Hi, Just took deliver of a Blitz SBC i-d and Power Meter i-d and am currently looking through the instructions and it says that the controller will not drop the boost pressure below the stock boost pressure. Does this mean that I cannot adjust the pressure below 14psi that my car is currently set to??? If this is the case is there anything I can do to allow me to adjust the boost pressure lower so I have more adjustment . I would ideally like to be able to take boost from 7psi or lower to about 17psi max. Zedhot :confused:

How to remove my OSR balljoint out of its assy' ???? With Hi-cas........... any tools etc.......... cheers Andy tt.

Right I know I asked this before and Steve E told me that the fan only comes on at 105ºC and comes on full power at 110ºC so I presume when the temp is below that it is normal. I had a cambelt change and before then I it was running cool very rarely going over 80ºC and when it did it went no higher than 90º. Now after my cambelt change which the water pump was changed too, its getting to 100ºC too often. Today I was driving 50mph down the motorway at 2000rpm in 5th gear and the temp was about 95ºC. I accelerated to 70mph which was about 2500rpm for about 10 miles and the temp went up to 110ºC, when I started to get a little worried. Any help? …

Slap me if im asking a dumb question, but.......... Is it possible to increase the amount the rear wheels turn??? Pete

Help! Ive just bought an early import 1990 ZX and it has lap belts in the back. My ex-wife has decided she won't let the kids go in it unless I fit 3-point shoulder belts! Is this possible? Are there places in the UK that would fit them for me? Thanks in advance for any help, Mythix.

So its getting dark and I have checked all my lights. RH Headlight Bulb is Off. Fuse OK So how do I get to the Bulb ! Any help appreciated Cheers Ginja
